In the container manufacturing sector, the deal is massive for several reasons. Firstly, it’s the end result of decades of intense competition between two long-time historical rivals constantly battling for market share.

Dart Container already commanded about half of the global market in foam cups (no doubt you have used their ubiquitous white foam cups before). In addition to its instantly recognizable red solo cups, Solo Cup makes plates, cutlery, take-out containers, and other similar products, under the Solo, Sweetheart, Creative Carryouts, and Bare brand names.

Another reason this deal is notable is because of the veil of secrecy that has hovered over privately owned Dart Container over the years. The king of cups is notoriously protective over the way it manufactures its products. The Dart family never patented the cup-making machine they developed, and this allowed them to avoid revealing how it works. The company, which was founded in 1960 by chairman William A. Dart and his father William F. is under the control of W.A. Dart’s sons, CEO Bob and president Ken.

In a surprise move (keeping in mind its history), Dart has denounced its secret ways, leapt into the public sphere, and swallowed up its largest rival. This means the next time you reach for a plastic or foam cup, you will more than likely be using one of Dart’s long list of products.

When it comes to securing its place atop its industry, there is no doubt Dart has hit the bullseye.
